Answer:
This is due to lactic acid accumulation in Emma's leg muscles.
Explanation:
In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.
This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

Answer:
B. The chimp and human are the most closely related organisms with the fewest differences in their amino acid sequence
Explanation:
This question shows a table containing the amino acid sequence of haemoglobin protein in different organisms. According to the table attached, a total of 15 amino acids are represented for each organism. A very reliable evidence that shows the relationship between organisms i.e. how related they are, is their DNA SEQUENCE.
Since the amino acid sequence of the protein in an organism is determined by the DNA sequence, organisms with very similar amino acid sequence are said to be CLOSELY RELATED. Hence, the similar the DNA sequence, the closer the relationship between organisms. In this case, the chimp and human have the same set of amino acids in their sequences, hence, they are the most closely related organisms with the fewest differences in their amino acid sequence.
Answer:
The arteries are the large blood vessels that carry blood from the heart to all the organs and muscles of the body, to give them the energy and oxygen they need. The arteries manage the flow of blood by controlling the speed and direction it flows in. Opening and closing different arteries affects your blood pressure
